To write or erase this memory type, you need a device called a PROM burner. A single byte of a data or the entire contents of device can be erased. EEPROM (Electrically Erasable Programmable Read Only Memory): EEPROM can be burned (programmed) and erased by first electrical waves in a millisecond.This memory type retains its contents until it exposed to intense ultraviolet light that clears its contents, making it possible to reprogram the memory. EPROM (Erasable Programmable Read Only Memory): EPROM is pronounced ee-prom.PROM can be programmed by PROM burner and by blowing internal fuses permanently. The significant difference between a ROM and a PROM is that a ROM comes with pre-written by the computer manufacturer whereas PROM manufactured as blank memory. Unlike ROM, PROMs retain their contents without the flow of electricity. It can be programmed only be done once and read many. PROM(Programmable Read Only Memory): PROM stands for programmable ROM.There is generally Three broad type of ROM: ROM comes with pre-written by the computer manufacturer to hold the instructions for booting-up the computer. It is similar to the RAM that is accessed by the CPU. ROM is an essential chip with permanently written data or programs. ROM is “Non-Volatile Memory” that retains data without the flow of electricity. Moreover, it is also slower and consumes less power than SRAM. The DRAM is cheaper, but it can store much more information. The Data is Refreshed Periodically to maintain in it. Dynamic Random Access Memory (DRAM): It is another form of RAM used as Main Memory, its retains information in Capacitors for a short period (a few milliseconds) even though the computer powered.It is faster compared to DRAM due to the latching arrangement, and they use 6 transistors per data bit as compared to DRAM, which uses one transistor per bit. As technically, SRAM uses more transistors as compared to DRAM. It used as Cache Memory in a computer system. SRAM is more expensive and consumes more power than DRAM. It retains data in latch as long as the computer powered. Redmi Note 5 Pro ( India) and Redmi Note 5 (Global) runs on MIUI 10.3.1 stable based on Android Pie 9. 5 Software edit Redmi Note 5 (China) runs on MIUI 10 based on Android Oreo 8.1.0. Static RAM: Static RAM is the form of RAM and made with flip flops and used for primary storage are volatile. Redmi Note 5 (Global) Camera Redmi Note 5 comes with 3GB or 4GB RAM and 32GB or 64GB expandable storage memory. Features 5.7 display, Exynos 7420 Octa chipset, 16 MP primary camera, 5 MP front camera, 3000 mAh battery, 128 GB storage, 4 GB RAM, Corning Gorilla Glass 4.
